- A new programmable charge coupled device (CCD) detector based on the CAMAC (Computer Automated Measurement and Control) modular system and coupled to a MircoVax 3 computer has been developed for time-resolved synchrotron experiments. The programmability of the electronics allows one to use many kinds of CCD chip. Moreover, different detector modes can be chosen according to the time scale of the experiment. Various time-resolved x-ray scattering experiments have already been performed at NSLS and CHESS with this imaging system. For example, a real-time study of the early stages of crystallization of the amorphous metallic alloy Fe₈₀B₂₀ was carried out at the X6 beamline at NSLS. Here a spin melt ribbon of the amorphous metal was resistively heated in stages in 600°C and the crystallization observed on the CCD. The detector angular acceptance of 3° allowed for the observation of the evolution of the α-Fe, and Fe₃B and the Fe₂B phases simultaneously on a minute time scale.
